128 NOTES ON AUSTRALIAN COLEOPTERA, 



sides, and with irregular longitudinal fovepe near sides. Elytra 

 slightly convex, broadly ovate, wider than and just twice as long 

 as prothorax; shoulders rather squarely rounded and wider than 

 prothorax at base, sides gradually widening behind till near 

 apical declivity ; surface without definite costae, or with two 

 ill-defined costae on each elytron, coarsely and irregularly aluta- 

 ceous, with reticulation larger at base, becoming obsolete at apex, 

 intervals coarsely foveate-punctate; lateral border narrow, only 

 evident from above at shoulder and apex, and without lateral 

 gutter; a single row of punctures on sides of the same size as the 

 punctures on the intervals. Prosternum trilobed, produced a 

 little backward and rounded at apex; the whole underside, with 

 femora and tibise, finely and rather closely punctured; all tibise 

 straight and minutely spinose at apex. Tarsi and extreme apex 

 of tibise sparsely clothed with pale reddish hairs. Dimensions — 

 16 X 8*3 mm. 



Hah — Walcha, New South Wales. 



Two specimens kindly given to me (and collected) by Dr. E. W. 

 Ferguson, one in a mutilated condition and without tarsi. The 

 type-specimen has moderately dilated tarsi, but is without any 

 marked sexual characters. The species differs considerably from 

 S. eJongatulus Macl., and S. clathratus Blackb., in its widely 

 rounded prothorax, more robust and dilated body, and irregular 

 reticulate sculpture, as compared wich the distinct costte of the 

 latter two species. 



OSPIDUS PAROPSOIDES, n.sp. 



Ovate, very convex, dull metallic purple-bronze. 



Head and antennae in structure similar to 0. chysomeloides 

 Pasc, but more closely and coarsely rugose, and with the whole 

 surface less nitid. Prothorax more than twice as wide as long 

 (3x7 mm.), widest at base, apex emarginate, anterior angles 

 rounded but protruding considerably in front of the eyes ; 

 explanate margins flat, wide and rugose. Disc very convex, more 

 finely and closely rugose than margins, lightly impressed in the 

 middle and near the base on each side of middle; base bisinuate;
